hartnn · Answer

addition property of equality :
if x=y 
then adding 'z' to both sides gives
x+z=y+z
what did u not get in this ?

hartnn · Answer

example : 
if x-3 = y 
then adding 3 to both sides will give you :
x-3+3 = y+3 ---- > x=y+3

anonymous · Answer

i have an example solve x -4=20 for x

hartnn · Answer

add 4 on both sides, what you get ?
